État de la populationTexte officiel évaluation IUCNExpert

Scleria chevalieri was collected in 1929 near Rufisque by August Chevalier, close to Dakar. Another herbarium specimen is known from the Casamance region, but the collection date and detailed locality are missing. There were several botanical excursions in the coastal regions of Senegal, but the species has not been found again. This species is now considered Extinct, as the last specimen was collected more than 90 years ago despite subsequent searches.

Description complète des menacesTexte détaillé évaluation IUCNExpert

The type locality can still be found near Rufisque, but it is currently in bad condition. There are gardens near the swamps and local people use the water for irrigation. This has resulted in most parts of the swamp being drained, primarily for cultivation. Only the deepest part of the swamp remains, with Typha vegetation (A. Mesterházy pers. obs.).
